In the arrangement shown, asone example, step 86 forms a generally flat and planar surface that alsoextends in approximate perpendicular alignment to the planes formed byopposing sides 80. In the arrangement shown, as one example, the depthor thickness of lower portion 28 is greater forward of step 86, and thedepth or thickness of lower portion 28 is less rearward of step 86. Inthe arrangement shown, as one example, step 86 connects at its upper endto the rearward end of resting surface 84, step 86 connects at itsoutward sides to sides 80, and step 86 connects at its lower end to theforward end of platform 88.

In the arrangement shown, as one example, a platform 88 is positionedrearward of step 86. Platform 88 forms a generally flat and planarsurface that extends in approximate parallel alignment to the planeformed by resting surface 84. In the arrangement shown, as one example,the plane formed by platform 88 extends in approximate perpendicularalignment to the plane formed by step 86. In the arrangement shown, asone example, the plane formed by platform 88 extends in approximateperpendicular alignment to the plane formed by opposing sides 80. In thearrangement shown, as one example, platform 88 connects at its forwardend to the lower end of step 86, platform 88 connects at its outwardsides to sides 80, and platform 88 connects at its rearward end to theupper end of rearward end 82.

In the arrangement shown, as one example, platform 88 of lower portion28 includes a slot 90 therein. In the arrangement shown, as one example,slot 90 is generally centrally positioned within lower portion 28 whenviewed from above or below and extends the majority of the distancebetween rearward end 82 and step 86. Slot 90 is configured to receiveand hold the lower end of center support 34 of upright assembly 32therein so as to facilitate secure attachment of center support 34 tobase 26. In the arrangement shown, as one example, once the lower end ofcenter support 34 is inserted into slot 90, the lower end of centersupport 34 is screwed or bolted to the lower portion 28 of base 26 usingone or more fasteners that extend laterally through holes 92 in lowerportion 28 of base 26, as well as through the lower end of centersupport 34 held within slot 90, thereby securely attaching the lower endof center support 34 to lower portion 28 of base 26.

In the arrangement shown, as one example, platform 88 also includes aplurality of through holes 94 therein. In the arrangement shown, as oneexample, through holes 94 are positioned just inward of each corner ofplatform 88 when viewed from above or below and extend verticallythrough lower portion 28 of base 26. Through holes 94 are configured toreceive fasteners therein that are configured to extend through andattach a platform of the lower end of upright assembly 32 to theplatform 88 of lower portion 28 of base 26 thereby securely attachingthe lower end of upright assembly 32 to lower portion 28 of base 26.

In the arrangement shown, as one example, the lower side 98 of lowerportion 28 forms a generally flat and planar surface that is configuredto facilitate stable support when the lower side 98 of self-adjustingpocket hole jig system 10 is placed on a flat work surface to be used ina vertical manner. In the arrangement shown, as one example, thegenerally flat planar surface of lower side 98 of lower portion 28 isformed by a lower end of a plurality of structural supports 100 thatextend across and throughout the base 26, including lower portion 28 aswell as backstop 30. In the arrangement shown, as one example, the planeformed by lower side 98 extends in approximate parallel spacedrelationship to the planes of resting surface 84 and platform 88. In thearrangement shown, as one example, the plane formed by lower side 98extends in approximate perpendicular alignment to the plane formed bysides 80 as well as the plane formed by rearward end 82.

In the arrangement shown, as one example, a receiver 102 isapproximately centrally positioned at the intersection of step 86 andplatform 88. Receiver 102 is formed of any suitable size, shape anddesign and is configured to receive and hold onto the lower end of firstreturn spring 50 of clamping assembly 38. In the arrangement shown, asone example, receiver 102 includes a generally cylindrical collar 104that extends upward and rearward at an angle away from backstop 30 ofbase 26. In the arrangement shown, as one example, a cross-shaped member106 extends upward and rearward from the upper end of the collar. Inthis arrangement, the upper surface of collar 104 is configured toreceive and engage the lower end of first return spring 50 while thecross-shaped member 106 is configured to extend within the hollowinterior of the lower end of return spring 50, thereby holding it inplace. Any other configuration is hereby contemplated for use forholding first return spring 50 in place such as a simple post, acircular recess in lower portion 28 of base 26, or any other connectionmember.

In the arrangement shown, as one example, the forward end of lowerportion 28 connects to the lower end of backstop 30.

In the arrangement shown, as one example, backstop 30 includes aclamping surface 108 that is generally flat and planar in shape. In thearrangement shown, as one example, clamping surface 108 faces rearward.In the arrangement shown, as one example, the plane formed by clampingsurface 108 extends in approximate perpendicular alignment to the planesof sides 80 of base 26 as well as to the plane formed by resting surface84. In the arrangement shown, as one example, the outward ends ofclamping surface 108 connect to the rearward end of sides 80 of backstop30, and the lower end of clamping surface 108 connects to the forwardend of resting surface 84. In the arrangement shown, as one example,clamping surface 108 is configured to engage and support a forward sideof a workpiece 24 when the workpiece 24 is clamped against backstop 30.To facilitate support of workpiece 24, clamping surface 108 forms agenerally flat and planar rearward facing surface of backstop 30 at theforward end of resting surface 84. In the arrangement shown, as oneexample, the plane formed by clamping surface 108 extends in approximateperpendicular alignment to the plane formed by upper end 110 of backstop30. In the arrangement shown, as one example, the upper end of clampingsurface 108 connects to the rearward end of upper end 110.

In the arrangement shown, as one example, backstop 30 includes an upperend 110 that is generally flat and planar in shape. In the arrangementshown, as one example, the plane formed by upper end 110 extends inapproximate perpendicular alignment to the planes of sides 80 of base 26as well as clamping surface 108. In the arrangement shown, as oneexample, the outward ends of upper end 110 connect to the upper ends ofsides 80.

In the arrangement shown, as one example, the forward side 112 ofbackstop 30 forms a generally flat and planar surface that is configuredto facilitate stable support when the forward side 112 of backstop 30 ofself-adjusting pocket hole jig system 10 is placed on a flat worksurface to be used in a horizontal manner. In the arrangement shown, asone example, the generally flat planar surface of forward side 112 oflower portion 28 is formed by a forward end of a plurality of structuralsupports 100 that extend across and throughout the base 26, includinglower portion 28 as well as backstop 30. In the arrangement shown, asone example, the plane formed by forward side 112 of backstop 30 extendsin approximate parallel spaced relationship to the plane formed byclamping surface 108. In the arrangement shown, as one example, theplane formed by forward side 112 of backstop 30 extends in approximateperpendicular alignment to the plane formed by sides 80 as well as theplane formed by upper end 110.

In this way, the configuration of base 26 facilitates stable placementof and use of self-adjusting pocket hole jig system 10 in a verticalmanner, when resting on lower side 98. In this way, the configuration ofbase 26 facilitates stable placement of and use of self-adjusting pockethole jig system 10 in a horizontal manner, when resting on forward side112.

In the arrangement shown, as one example, the distance between lowerside 98 and resting surface 84 is approximately the thickness of aconventional 2×4. Similarly, in the arrangement shown, as one example,the distance between forward side 112 and clamping surface 108 isapproximately the thickness of a conventional 2×4. As such, aconventional 2×4 can be used to make jigs or other support members whenusing self-adjusting pocket hole jig system 10 to drill pocket hole jigsregardless of whether the self-adjusting pocket hole jig system 10 isused in a vertical orientation or a horizontal orientation.

In the arrangement shown, as one example, base 26 is a formed of asingle monolithic member that is formed by any process such as molding,injection molding, casting, forming, machining, or through any othermanufacturing process. In one arrangement, base 26 is formed of a solidmember. In another arrangement, as is shown, so as to provide therequisite strength while minimizing weight and material usage, base 26is skeletonized and includes structural supports 100 that extends acrossthe lower side 98 and forward side 112 of base 26. In anotherarrangement, base 26 is formed of a plurality of components that areconnected to one another by fastening means such as adhesive, gluing,bolting, screwing, snap fitting, friction fitting or any other manner ormethod or means or the like processes. In one arrangement, base 26 isformed of a plastic or composite material. In another arrangement, base26 is formed of a metallic material. In another arrangement, base 26 isformed of a plastic or composite material that includes metallic supportmembers that extend through the base 26 thereby providing additionalstrength and rigidity.

In the arrangement shown, as one example, upright assembly 32 isconnected to base 26.

Upright Assembly:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes an upright assembly 32. Upright assembly 32 may beformed of any size, shape and design and is configured to providesupport for clamping assembly 38, handle 44 and drill guide assembly 62and facilitate clamping of workpiece 24 in self-adjusting pocket holejig system 10.

Center Support:

In the arrangement shown, as one example, upright assembly 32 includes acenter support 34. Center support 34 is itself formed of any suitablesize, shape and design and is configured to connect to lower portion 28of base 26 and to provide support for upright assembly 32. In thearrangement shown, as one example, center support 34 is formed ofgenerally planar member that extends a length between an upper end 114and a lower end 116. In the arrangement shown, as one example, the lowerend 116 includes a pair of feet that are laterally spaced from oneanother a distance and include a hole 118. In the arrangement shown, asone example, lower end 116 of center support 34 is configured to beinserted within slot 90 of lower portion 28 of base 26 and areconfigured to receive fasteners, such as screws or bolts, that extendthrough a portion of the base 26 thereby rigidly and securely attachingthe lower end 116 of center support 34 to lower portion 28 of base 26.

In the arrangement shown, as one example, center support 34 includes amain body 120 that extends between lower end 116 and upper end 114. Inthe arrangement shown, as one example, main body 120 has a generallyflat and straight and square forward edge and a generally flat andstraight and square rearward edge that extend in approximate parallelspaced relation to one another from lower end 116 to upper end 114,albeit at an angle to vertical. That is, while backstop 30 risesgenerally vertically upward from lower portion 28 of base 26, main body120 of center support 34 extends rearward at an angle as it extendsupward from lower portion 28 of base 26.

In the arrangement shown, as one example, an arm 122 extends rearwardfrom main body 120 near the lower end 116 thereby broadening the stanceof the lower end 116 of center support 34 thereby increasing the supportfor upright assembly 32, and increasing the surface area of engagementbetween center support 34 and lower portion 28 of base 26 which enhancesstrength and rigidity of upright assembly 32. In the arrangement shown,as one example, a triangular shaped opening is positioned in the lowerportion of center support 34 between main body 120 and arm 122 to reduceweight and material usage.

In the arrangement shown, as one example, an arm 124 extends forwardfrom the forward side of main body 120 adjacent the lower end 116 ofcenter support 34 and includes a hole therein. This arm, and itsassociated hole, serves as a connection point for the lower end ofsecond return spring 52.

In the arrangement shown, as one example, a slot 126 is positioned incenter support 34 adjacent the upper end 114. Slot 126 extends a lengthin approximate parallel spaced relation with the length of main body 120and facilitates connection of components of clamping assembly 38 tocenter support 34, while also allowing vertical movement of thesecomponents of clamping assembly 38 relative to the length of slot 126.

In one arrangement, center support 34 is formed of a solid metallicmaterial, so as to maximize strength and rigidity and durability as wellas to provide a long useful life. The use of a solid metallic member forcenter support 34 also facilitates crisp and firm locking of clutchplates 48 on center support 34. In some embodiments, other size shape ordesign as well as any other material is hereby contemplated for use forcenter support 34.

Upper Link:

In the arrangement shown, as one example, clamping assembly 38 includesan upper link 40. Upper link 40 is itself formed of any suitable size,shape and design and is configured to connect to clutch housing 46 onits upper end and to connect to lower link 42 on its lower end.

In the arrangement shown, as one example, upper link 40 is formed of apair of generally symmetric members wherein one member is positioned oneach side of center support 34. The upper end of upper link 40 includesa hole 128 that receives clamp force adjustment mechanism 54 therein.More specifically, in the arrangement shown, hole 128 in the upper endof upper link 40 receives rod 58 of clamp force adjustment mechanism 54there through. Rod 58 of clamp force adjustment mechanism 54 extendsthrough the hole 128 in the upper end of upper link 40 on each side ofcenter support 34. Rod 58 also extends through slot 126 in centersupport 34, which facilitates constrained of limited upward and downwardmovement of the upper end of upper link 40 on center support 34.

In the arrangement shown, as one example, the upper end of upper link 40is generally rounded when viewed from the side. In the arrangementshown, as one example, a protrusion 130 extends upward from thegenerally rounded upper end of upper link 40 at the rearward side ofupper link 40. This protrusion 130 breaks the rounded surface of theupper end of upper link 40 as protrusions 130 rise up from and out ofthe upper end of upper link 40. Protrusions 130 are configured to engagethe lower side of clutch plates 48. When protrusions 130 engage clutchplates 48 the clutch plates 48 cannot lock onto center support 34. Incontrast, when protrusions 130 disengage clutch plates 48 the clutchplates lock onto center support 34. As upper link 40 rotates between anunclamped position and a clamped position, protrusions 130 move betweenengagement with clutch plates 48 and disengagement with clutch plates48.

In the arrangement shown, as one example, arms 132 are connected to theupper end of upper link 40 and extend forward therefrom. Arms 132 areconfigured to engage and hold the upper end of second return spring 52,such as through insertion of a portion of second return spring 52through a hole in the forward end of arms 132, however any otherconnection method or manner is hereby contemplated for use between arms132 and second return spring 52. In this way, the upper end of secondreturn spring 52 connects to the forward end of arms 132 and the lowerend of second return spring 52 connects to arm 124 of center support 34.In this way, second return spring 52 is stretched between arms 132 ofupper link 40 and arm 124 of center support 34 which has the effect ofbiasing or pulling the upper end of upper link 40 downward which causesthe handle 44 to naturally move upward when in an unclamped position.

In the arrangement shown, as one example, upper link 40 is formed of apair of members wherein one member is positioned on each side of centersupport 34. The upper end of upper link 40 includes a hole 128 thatreceives clamp force adjustment mechanism 54 therein. More specifically,in the arrangement shown, hole 128 in the upper end of upper link 40receives rod 58 of clamp force adjustment mechanism 54 there through.Rod 58 of clamp force adjustment mechanism 54 extends through the hole128 in the upper end of upper link 40 on each side of center support 34.Rod 58 also extends through slot 126 in center support 34, whichfacilitates constrained of limited upward and downward movement of theupper end of upper link 40 on center support 34.

In the arrangement shown, as one example, the lower end of upper link 40includes a hole 134 that receives a pivot point 136 therein. Pivotpoints 136 connect the lower end of upper links 40 to the upper end oflower links 42. In this way, pivot point 136 facilitates relativeangular rotation of upper links 40 with respect to lower links 42 aroundthe axis of rotation formed by pivot point 136.

In the arrangement shown, as one example, the lower end of upper link 40includes a stop bar 138 that extends across the opposing sides of upperlink 40 just rearward of hole 134 and pivot point 136. In thearrangement shown, as one example, stop bar 138 is a cylindrical rodthat extends in approximate perpendicular alignment to the planes formedby upper link 40. In the arrangement shown, as one example, stop bar 138extend through holes in each side of upper link 40 and is locked intoplace in the holes in upper link 40. In the arrangement shown, as oneexample, when clamping assembly 38 is a clamped position, with handle 44in a fully downward position or a fully clamped position, the forwardside of stop bar 138 engages the rearward side of center support 34.This engagement between stop bar 138 and center support 34 defines theover-center condition of a fully clamped position. This engagementbetween stop bar 138 and center support 34 prevents the clampingassembly 38 moving too far forward, which can cause too much pressure onworkpiece 24 and/or can risk breaking components of system 10.

In the arrangement shown, as one example, the lower end of upper link 40includes an extension 140. In the arrangement shown, as one example,extension 140 extends rearward from the lower end of upper link 40 andfacilitates connection to handle 44 at the rearward end of extension140. In the arrangement shown, as one example, the opposing sides ofupper link 40 neck or bend inward toward one another and connect to oneanother just before handle 44 connects to upper link 40. In this way,the opposing sides of upper link 40 join to one another at the rearwardend of extension 140 forming upper link 40 into a single joinedcomponent. In the arrangement shown, as one example, the side ofextension 140 are connected to one another by any manner, method ormeans such as by stamping, press fitting, friction fitting, screwing,bolting, gluing, welding, adhering, or by any other manner, method ormeans or the like.

Handle:

In the arrangement shown, as one example, handle 44 connects to therearward end of extension 140 of upper link 40. Handle 44 is formed ofany suitable size, shape and design and is configured to facilitatecomfortable, easy and ergonomic clamping and unclamping of the system10. In the arrangement shown, as one example, handle 44 is formed of agenerally square or rectangular shaped pad when viewed from above thatincludes a slightly recessed upper surface 142. In the arrangementshown, as one example, the rearward end of handle 44 includes an angledsection 144 that angles downward and outward as it extends away fromupper surface 142.

The large surface area of upper surface 142 provides ample area tocomfortably apply pressure and downward force onto handle 44 andclamping assembly 38 thereby facilitating movement from a non-clampingposition to a clamping position wherein workpiece 24 is clamped betweenthe clamping face 74 of drill guide block 72 and clamping surface 108 ofbackstop 30. The down turned angled section 144 provides an easy andcomfortable place for a user to grasp handle 44 and pull upward to movethe handle 44 and clamping assembly 38 form a clamped position to anon-clamped position.

Handle 44 is connected to extension 140 of upper link 40 by any manner,method or means such as by stamping, press fitting, friction fitting,screwing, bolting, gluing, welding, adhering, molding-onto extension140, or by any other manner, method or means or the like.

Lower Link:

In the arrangement shown, as one example, clamping assembly 38 includesa pair of lower links 42. Lower links 42 are formed of any suitablesize, shape and design and is configured to connect to the lower end ofupper links 40 at their upper end and connect to arms 66 of drill guideassembly 62 on their lower end.

In the arrangement shown, as one example, lower links 42 are formed ofgenerally planar members that extend from an upper end to a lower endand includes a hole 146 in each end. In the arrangement shown, as oneexample, hole 146 in the upper end of lower links 42 receives a pivotpoint 136 that connects to hole 134 in the lower end of upper link 40and facilitates relative angular rotation of upper links 40 with respectto lower links 42 around the axis of rotation formed by pivot point 136.

In the arrangement shown, as one example, hole 146 in the lower end oflower links 42 receives a pivot point 146 that connects to hole 148 inthe rearward end of arms 66 of drill guide assembly 62 and facilitatesrelative angular rotation of lower links 42 with respect to arms 66 ofdrill guide assembly 62. In this way, movement of lower links 42facilitates movement of drill guide assembly 62 along the length ofupright assembly 32.

Clutch Housing:

In the arrangement shown, as one example, clamping assembly 38 includesa clutch housing 46. Clutch housing 46 is formed of any suitable size,shape and design and is configured to facilitate movement along thelength of upright assembly 32 and center support 34 while facilitatingselective locking along the length of upright assembly 32 and centersupport 34 so as to facilitate automatic clamping of workpieces 24 ofvarious thicknesses.

In the arrangement shown, as one example, clutch housing 46 includes anupper wall 150 that includes a slot 152 therein that is sized and shapedto fit over the upper end 114 of center support 34. The plane formed byupper wall 150 extends in approximate perpendicular alignment to thelength of main body 120 of center support 34. In the arrangement shown,as one example, clutch housing 46 includes a pair of opposing sides 154that extend downward in approximate parallel spaced relation to oneanother as they extend downward from the upper wall 150 of clutchhousing 46. Sides 154 extend in approximate parallel spaced relation tothe sides of main body 120 of center support 34. In the arrangementshown, as one example, clutch housing 46 includes a forward wall 156 andrearward wall 158 that extend downward in approximate parallel spacedrelation to one another as they extend downward from the upper wall 150of clutch housing 46. In this way, upper wall 150, sides 154, forwardwall 156 and rearward wall 158 of clutch housing 46 form a hollowinterior that houses and holds clutch plates 48 and bias member 160therein. Clutch housing 46 slides along the length of center support 34between a fully raised position, or a fully unclamped position, and afully lowered position, or a fully clamped position as handle 44 andupper link 40 and lower link 42 themselves move between a fully raisedposition, or a fully unclamped position, and a fully lowered position,or a fully clamped position.

In the arrangement shown, as one example, clutch housing 46 houses oneor more clutch plates 48 within the hollow interior of clutch housing 46as well as bias member 160 which applies a spring bias force upon clutchplates 48 that causes clutch plates 48 to bind or lock onto centersupport 34 when the support of the protrusion 130 of upper link 40 isremoved. In the arrangement shown, as one example, two clutch plates 48are used which are placed in parallel relation to one another within thehollow interior of clutch housing 46, however any number of clutchplates 48 are hereby contemplated for use such as one, two, three, four,five, six, seven, eight, nine, ten or more. The more clutch plates 48that are used the greater the amount of locking force can be held by theclutch housing 46. In the arrangement shown, as one example, whenmultiple clutch plates 48 are used they are laid on top of one anotherin frictional engagement with one another, however each clutch plate 48may slide slightly relative to one another when they are tilted withrespect to center support 34.

In the arrangement shown, as one example, clutch plates 48 are generallyplanar members that, like upper wall 150 of clutch housing 46, includeslots through their approximate center that allow center support 34 toextend through clutch plates 48. In the arrangement shown, as oneexample, when the plane formed by clutch plates 48 are in approximateperpendicular alignment to the length of the center support 34 theclutch plates 48 move freely along the length of center support 34. Incontrast, in the arrangement shown, as one example, when the planeformed by clutch plates 48 angles out of perpendicular alignment to thelength of the center support 34 the clutch plates 48 lock onto centersupport 34. This occurs when the support of the protrusion 130 of upperlink 40 is removed, by rotation of handle 44, thereby allowing biasmember 160 to force one end of clutch plates 48 out of perpendicularalignment with the length of center support 34. In the arrangementshown, as one example, bias member 160 is a spring positioned betweenthe lower surface of upper wall 150 and the upper surface of theupper-positioned clutch plate 48 that forces the rearward end of clutchplates 48 downward on a side opposite where protrusion 130 forces clutchplates 48 upward.

Clamp Force Adjustment Mechanism:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes a clamp force adjustment mechanism 54. Clamp forceadjustment mechanism 54 may be formed of any size, shape and design andis configured to facilitate user adjustment of clamping force orclamping pressure that self-adjusting pocket hole jig system 10 applieson workpieces 24 of various thicknesses. That is, regardless of thethickness of workpiece 24, self-adjusting pocket hole jig system 10 willapply approximately the same amount of clamping force on workpiece 24 byautomatically adjusting the internal components of self-adjusting pockethole jig system 10 in response to the thickness of workpiece

In the arrangement shown, as one example, clamp force adjustmentmechanism 54 includes a knob 56 connected to a rotating rod 58 that isconnected to and/or includes a cam surface 60. In the arrangement shown,as one example, knob 56 is positioned on an outward side of covers 36 ofupright assembly 32 so as to facilitate easy adjustment by a user. Inthe arrangement shown, as one example, knob 56 and/or rod 58 that knob56 is connected to extend through slot 162 in at least one cover 36. Inthe arrangement shown, as one example, slot 162 in covers 36 ispositioned adjacent slot 126 in center support 34, in this way, asclutch housing 46 travels along center support 34, knob 56 is able tomove within slot 162 in covers 36.

Knob 56 connects to rod 58 which is connected to and/or includes a camsurface 60. In the arrangement shown, as one example, rotating rod 58extends through holes 164 in the lower end of sides 154 of clutchhousing 46 as well as through holes 128 in the upper end of upper link40. In this arrangement, rod 58 also extends through slot 126 in centersupport 34 thereby connecting opposing sides 154 of clutch housing 46while extending through center support 34. In this way, rod 58 connectsknob 56, cam surface 60, upper ends of upper link 40 of clampingassembly 38 and sides 154 of clutch housing 46 while also extendingthrough center support 34.

In the arrangement shown, as one example, cam surface 60 is positionedbetween a stop 166 on the upper side and lower side of cam surface 60.In the arrangement shown, as one example, cam surface 60 has a generallycircular exterior surface that is captured between the opposing stops166 which are positioned on the upper side and lower side of cam surface60 within tight and close tolerances, and in some arrangements inengagement with cam surface 60 while also allowing for the rotation ofcam surface 60 between stops 166. In the arrangement shown, as oneexample, rod 58 and knob 56 are connected in an off-center alignment tothe circular exterior surface of cam surface 60 such that when knob 56and rod 58 are rotated, cam surface 60 rotates between the upper andlower stops 166. Alternatively, a non-circular lobe maybe used as camsurface 60. This rotation of cam surface 60, due to the off-centerconnection to rod 58 causes the relative position of the upper end ofupper link 40 to change relative to clutch housing 46. Essentially,rotation of knob 56 causes rotation of cam surface 60 which causes theupper end of upper link 40 of clamping assembly 38 to move up or down,depending on the direction of rotation, relative to clutch housing 46and clutch plates 48.

That is, effectively, rotation of knob 56 in a first direction lengthensthe linkage whereas rotation of knob 56 in a second direction, oppositethe first direction, shortens the linkage. This lengthening orshortening of the length of the linkage of clamp force adjustmentmechanism 54 affects the clamping force or clamping pressure applied toworkpiece 24.

As is further described herein, the sooner the protrusion 130 disengagesthe clutch plates 48 the sooner the clutch plates 48 lock onto thecenter support 34. The sooner the clutch plates 48 lock onto the centersupport 34 the greater the distance clamping assembly 38 travels to goto an over-center clamped position. The sooner the clutch plates 48 lockonto the center support 34 the sooner the clamping face 74 of the drillguide block 72 begins applying a clamping force on workpiece 24. Thesooner the clutch plates 48 lock onto the center support 34 the greaterthe clamping force applied to the workpiece 24.

Thin Portion of Cam Surface:

As such, this translates into when the thinner the portion of camsurface 60 is positioned between the upper stop 166 and rod 58 thehigher the protrusion 130 of upper link 40 relative to clutch housing 46and clutch plates 48 and therefore the greater the amount of engagementbetween protrusion 130 and clutch plates 48. As such, the handle 44 mustbe rotated further downward to disconnect protrusion 130 from clutchplates 48, at which point the clutch plates 48 lock onto the centersupport 34. As such, the handle 44 does not have as far to rotate afterdisconnection between protrusion 130 and clutch plates 48, and whenclutch plates 48 lock onto center support 34, to go to an over-centercondition. As such, less clamping pressure is applied to workpiece 24when clamping assembly 38 is in an over-center clamping position when athinner portion of cam surface 60 is positioned between upper stop 166and rod 58.

Thick Portion of Cam Surface:

In contrast, as such, this translates into when the thicker the portionof cam surface 60 is positioned between the upper stop 166 and rod 58the lower the protrusion 130 of upper link 40 relative to clutch housing46 and clutch plates 48 and therefore the less the amount of engagementbetween protrusion 130 and clutch plates 48. As such, the handle 44 doesnot rotate as far downward to disconnect protrusion 130 from clutchplates 48, at which point the clutch plates 48 lock onto the centersupport 34. As such, the handle 44 has farther to rotate afterdisconnection between protrusion 130 and clutch plates 48, and whenclutch plates 48 lock onto center support 34, to go to an over-centercondition. As such, more clamping pressure is applied to workpiece 24when clamping assembly 38 is in an over-center clamping position when athicker portion of cam surface 60 is positioned between upper stop 166and rod 58.

As such, in this way, clamp force adjustment mechanism 54 providesinfinite adjustment of clamping pressure for workpiece 24. As knob 56 isrotated in a direction that causes a decrease in the thickness of thecam surface 60 between rod 58 and upper stop 166 the lesser the amountof clamping pressure because protrusion 130 of upper link 40 disconnectsfrom clutch plates 48 later. As knob 56 is rotated in a direction thatcauses an increase in the thickness of the cam surface 60 between rod 58and upper stop 166 the greater the amount of clamping pressure becauseprotrusion 130 of upper link 40 disconnects from clutch plates 48sooner.

In the arrangement shown, as one example, cam surface 60 is formed of acylindrical plate positioned on the outward side of both opposing sides154 of clutch housing 46 around hole 164. In this arrangement, each ofthese cam surfaces 60 are connected to and rotated by rod 58. In thisarrangement, each of these cam surfaces 60 are captured between opposingupper and lower stops 166. In this way, placing a cam surface 60 on eachside 154 of clutch housing 46 provides balance to clutch housing 46 andaccurate and precise adjustment of clamping pressure. In this way,placing a cam surface 60 on each side 154 of clutch housing 46 providesaccurate and precise adjustment of each side of upper link 40 ofclamping assembly 38.

In the arrangement shown, as one example, only a single knob 56 extendsout of one side of clamping assembly 38. In an alternative arrangement,a knob 56 extends out of both sides of clamping assembly 38 therebyallowing for adjustment from both sides.

In one arrangement, detents are used in association with knob 56. Thesedetents allow a user to freely rotate knob 56 and its attached camsurface 60, however these detents provide user feedback throughresistance that help a user understand how far they have rotated knob56. These detents also help to hold knob 56 in place once set by a user.In this way, the use of detents in association with knob 56 provides aneasier to use and more accurate arrangement that better holds theuser-set position.

Covers:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes a pair of covers 36. Covers 36 may be formed of anysuitable size, shape and design and are configured to cover portions ofthe upright assembly 32 while also providing additional support forcenter support 34 as well as providing support to as well as a surfacefor drill guide assembly 62 to slide upon to move between annon-clamping position to a clamping position and vice versa.

In the arrangement shown, as one example, upright assembly 32 includes apair of covers 36 that are approximately symmetric to one another andconnect together along a seamline 168 that extends along the approximateforward-to-back center of clamping assembly 38. In this way, whenopposing left and right covers 36 are joined together they form a hollowinterior 170 that houses and holds center support 34, clutch housing 46and other portions of clamping assembly 38 and clamp force adjustmentmechanism 54 as is shown and described herein. That is, the generallysymmetric or mirror-image covers 36 join together along seamline 168 ina clamshell like manner.

In the arrangement shown, as one example, covers 36 include a forwardside 172 and an opposing rear side 174, exterior sides 176, an upperside 178 and a platform 180 at their lower end. In the arrangementshown, as one example, the forward side 172 is generally flat and planarand extends in approximate parallel spaced relation to the forward sideof main body 120 of center support 34. In this way, the flat and planarforward side 172 of the joined covers 36 serves as a sliding surface forthe rearward side of drill guide assembly 62 to slide over as it movesbetween a non-clamping position and a clamping position.

In the arrangement shown, as one example, platform 180 is connected tothe lower end of covers 36. Platform 180 is formed of any suitable sizeshape and design and is configured to connect to base 26 in a rigid andstable manner so as to added stability to upright assembly 32. In thearrangement shown, as one example, platform 180 is a generally planarmember that includes a plurality of through holes 182 therein. In thearrangement shown, as one example, when covers 36 are joined together,the combined platforms 180 form a generally square or rectangularperipheral edge when viewed from above or below that is configured tofit on platform 88 of lower portion 28 of base 26. In the arrangementshown, through holes 82 of platform 180 of covers 36 match up withthrough holes 94 in platform 88 of lower portion 28 of base 26. In thearrangement shown, as one example, covers 36 are installed on base 26 byaligning the through holes 182 in platforms 180 of covers 36 with thethrough holes 94 of platform 88 of lower portion 28 of base 26. Once inthis alignment, fasteners, such as screws or bolts or the like arepassed through the through holes 182 in platform 180 of covers 26 andinto the through holes 94 of platform 88 of lower portion 28 of base 26.When installed in this manner, platform 180 of covers 36 are infrictional planar engagement with platform 88 of lower portion 28 ofbase 26.

In the arrangement shown, as one example, opposing covers 36 include aplurality of through holes 184 that are used to join opposing covers 36.In the arrangement shown, as one example, when covers 36 are installedaround center support 34, clutch housing 46 and the other internalcomponents of system 10, and opposing covers 36 connect to one anotheralong seamline 168, through holes 184 in opposing covers 36 align withone another. Once in this alignment, fasteners, such as screws or boltsor the like are passed through the through holes 184 in opposing covers26 thereby joining opposing covers 36 in a locked arrangement. Affixingopposing covers 36 to one another also helps to hold and secure theinternal components of upright assembly 32 between coves 36. As oneexample, the upper end 114 of center support 34 is held within supports186 on the interior surfaces of covers 36 thereby securely locking theupper end 114 of center support 34 in place within covers 36. Theconnection of opposing covers 36 to one another as well as to centersupport 34 as well as to base 26 increases the strength and rigidity ofupright assembly 32.

In the arrangement shown, as one example, when covers 36 are joinedtogether they form a forward slot 186 in their forward side 172 thatreceives and allows arms 66 of drill guide assembly 62 to extend therethrough and allows for vertical motion of drill guide assembly 62relative to upright assembly 32. In the arrangement shown, as oneexample, when covers 36 are joined together they form a rearward slot188 in their rearward side 174 that receives and allows the extension ofupper links 40 and/or lower links 42 of clamping assembly 38 to extendthere through and allows for rotational motion of upper links 40 and/orlower links 42 therein. As handle 44 is moved upward or downwardportions of upper links 40 and/or lower links 42 move through rearwardslot 188 thereby facilitating clamping and unclamping. In thearrangement shown, as one example, covers 36 include a slot 162 in theirexterior sides 176 that receives clamp force adjustment mechanism 54 andallows the components of clamp force adjustment mechanism 54 that extendthrough slot 162 to vertically move as clutch housing 46 verticallymoves as handle 44 is moved upward or downward as upper links 40 and/orlower links 42 move thereby facilitating clamping and unclamping.

In the arrangement shown, as one example, a flange 190 extends outwardpast sides 176 at the forward side 172 of covers 36. In this way,flanges 190, which extend outward from each side of the forward side 172of covers 36 expands the surface area of the forward side 172 of uprightassembly 32. Flanges 190 also form a lip that extends past sides 176which is grasped by drill guide assembly 62. That is, flanges 190facilitate a connection point for drill guide assembly 62 and help tohold drill guide assembly 62 onto the forward side 172 of uprightassembly 32 while also allowing drill guide assembly 62 to slide alongforward side 172 of upright assembly 32. In the arrangement shown, asone example, when viewed along the length of flanges 190, flanges 190have a relatively square or rectangular shape that extends past forwardside 172 and sides 176.

In the arrangement shown, as one example, the lower end of centersupport 34 extends into base 26. In an alternative arrangement, aperpendicular member is connected to the lower end of center support 34that provides increased surface area for the lower end of center support34 to engage base 26. This also allows for the lower end of centersupport 34 to be placed on a work bench or other work surface withouthaving to cut out an area for the lower protrusions of center support34. This makes it easier to use the upright assembly 32 in a standalonemanner separated from a dedicated base 26. This also allows users tomake custom jigs out of a plurality of upright assemblies 32, such aswhen manufacturing cabinetry or furniture.

Drill Guide Assembly:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes a drill guide assembly 62. Drill guide assembly 62may be formed of any size, shape and design and is configured to movealong upright assembly 38 by way of operation of clamping assembly 38and handle 44 so as to facilitate clamping of workpiece 24 and drillingof pocket holes in workpiece 24. In the arrangement shown, as oneexample, drill guide assembly 62 includes a main body 64 having arms 66and an opening 68 therein as well as spring biased members 70 as well asother components and features as is described herein.

In the arrangement shown, as one example, main body 64 is formed of apair of halves 192 that are approximately symmetric to one another andconnect together to one another at a generally centrally positionedseamline 194. In the arrangement shown, as one example, side members 196are connected to the outward sides of halves 192. Side members 196 areformed of any suitable size, shape and design and are configured toenclose the outward end of halves 192. Halves 192 and side members 196may be connected to one another by any manner, method or means such asscrewing, bolting, welding, gluing, adhering, snap fitting, frictionfitting or the like or any combination thereof.

In the arrangement shown, as one example, side members 196 include anopening 198 that is positioned slightly upward and forward from opening68 that extends through side members 196 as well as halves 192. Opening198 is configured to hold spring biased members 70 therein. In thearrangement shown, as one example, spring biased members 70 are includea cover 200 that fits within the interior side of opening 198 and abiasing member 202 that is positioned between the interior surface ofcover 200 and the outward facing side of the halve 192 that cover 200 isassociated with. In the arrangement shown, as one example, biasingmember 202 is a spring that provides a bias force that forces cover 200outward. However, user applied pressure may move cover 200 inward whenthe spring bias force of biasing member 200 is overcome. In onearrangement, the rearward end of cover 200 connects to side members 196by a pair of opposed pivot points 201 on the upper end lower ends ofcover 200 that facilitate pivoting of the forward end of cover 200 onthe axis of rotation formed by the connection of pivot points 201 toside members 196. This arrangement also allows for some mechanicaladvantage over biasing member 202 and facilitates the inward motion ofthe forward end of covers 200 upon rotation on pivot points 201.

In the arrangement shown, as one example, the forward end of cover 200includes at least one lip 204 that includes a feature 206 thereon thatis configured to selectively attach to and hold drill guide block 72 tothe forward end of drill guide assembly 62. In the arrangement shown, asone example, lip 204 of cover 200 extends forward from the upper forwardend of main body 64 and feature 206 is positioned at the forward end oflip 204. This arrangement is configured to allow drill guide block 72 tolock onto the main body 62 of drill guide assembly 62 upon installationand prevents unintentional disassembly or separation of drill guideblock 72 from main body 64 of drill guide assembly 62. That is, whendrill guide block 72 is installed onto drill guide assembly 62 the shapeor angled surfaces of features 206 cause covers 200 to move inwardagainst the bias force of biasing member 202 until the feature 206clears a corresponding feature 208 on drill guide block 72, at whichpoint the bias force of bias member 202 pushes cover 200 outward therebylocking drill guide block 72 onto drill guide assembly 62.

To remove drill guide block 72 from drill guide assembly 62 a userapplies inward pressure against opposing covers 200 of spring biasmembers 70 thereby overcoming the bias force of biasing members 202.Upon overcoming the biasing force of biasing members 202, covers 200move inward. Once the feature 206 of lips 204 of covers 200 clear thecorresponding feature 208 of drill guide block 72, drill guide block 72may be removed from drill guide assembly 62. In this way, drill guideassembly 62 provides a quick and easy and convenient way to install andremove various drill guide blocks 72 without tools and by hand only.Swapping out drill guide blocks 72 allows for the use of different drillguide blocks 72 for different applications and various purposes.

In the arrangement shown, as one example, opening 68 extends throughdrill guide assembly 62 from side-to-side. That is, in the arrangementshown, as one example, opening 68 extends through opposing side members196 as well as opposing halves 192 of main body 64. In the arrangementshown, as one example, opening 68 is generally square or rectangular inshape when viewed from the side and extends in approximately aconsistent and continuous manner through drill guide assembly fromside-to-side. However any other size, shape or configuration of opening68 is hereby contemplated for use.

In the arrangement shown, as one example, a passageway 210 connects toopening 68. In the arrangement shown, as one example, passageway 210 isgenerally centrally positioned within the lower portion of main body 64of drill guide assembly 62. Passageway 210 forms an open path betweenthe forward side of halves 192 and connects to opening 68 within drillguide assembly 62. The forward end of passageway 210 connects to apassageway 212 that connects to bores 78 of drill guides 76 in drillguide block 72. In this way, the connection of passageway 212 in drillguide block 72 to passageway 210 in drill guide assembly 62 provides apath for woodchips, dust and debris generated during drilling to exitdrill guide assembly 62. This is true even though drill guide assembly62 is moveable along upright assembly 32.

In the arrangement shown, as one example, a connection point 214 ispositioned at the lower end of the forward side of main body 64.Connection point 214 is formed of any suitable size, shape and designand is configured to receive a connection point 216 in the lower end ofdrill guide block 72. In the arrangement shown, as one example,connection point 214 is a lip that forms an upwardly facing recess. Inthis arrangement, connection point 214 is configured to receive aprotrusion that serves as connection point 216 in drill guide block 72.In this way, the connection point 214 of drill guide assembly 62receives the connection point 216 in drill guide block 72 in matingarrangement, while also allowing for limited rotation of drill guideblock 72 relative to drill guide assembly 62. Once the connection point216 of drill guide block 72 is received within the connection point 214of drill guide assembly 62, the upward end of drill guide block 72 isrotated toward drill guide assembly 62 until the features 206 of covers200 lock on to features 208 of drill guide block 72. Once this occurs,the lower end of drill guide block 72 is secured to drill guide assembly62 by connection point 214 and the upper outward sides of drill guideblock 72 are secured to drill guide assembly 62 by features 206. In thisway a secure connection is made that holds drill guide assembly 62 anddrill guide block 72 together without the use of tools in a quick, easy,convenient and secure manner. That is, this installation may be made byhand only.

To remove drill guide block 72 from drill guide assembly 62, covers 200are depressed inward until the features 206 of covers 200 clear thecorresponding features 208 of drill guide block 72 at which point theupper end of drill guide block 72 is rotated downward until theconnection point 216 of drill guide block 72 is removed from theconnection point 214 of drill guide assembly 62. In this way, drillguide block 72 may be quickly, easily and conveniently removed fromdrill guide assembly 62 by hand only without the use of tools.

In the arrangement shown, as one example, the rearward side of drillguide assembly 62 includes a rear wall 218. In the arrangement shown, asone example, rear wall 218 is generally flat and planar and extends atan acute angle to clamping face 74 of drill guide block 72. That is,when viewed from the side, when the plane formed by clamping face 72extends vertically, the plane formed by rear wall 218 extends at lessthan ninety degrees. This angular arrangement is configured toaccommodate the angle of the forward side 172 of covers 36 of uprightassembly 32.

In the arrangement shown, as one example, a pair of slots 220 arepositioned at the outward sides of drill guide assembly 62. In thearrangement shown, as one example, slots 220 are formed by the rearwardend of side members 196 extending past rear wall 218 and then extendinginward toward one another a distance before terminating in a free andunattached end. In the arrangement shown, as one example, slots 220extend in parallel spaced relation to the plane of rear wall 218 andextend uninterrupted from the top end of drill guide assembly 62 to thelower end of drill guide assembly. In the arrangement shown, as oneexample, slots 220 are generally square or rectangular in shape whenviewed from above or below and are configured to receive the generallysquare or rectangular flanges 190 therein within close and tighttolerances while also allowing for sliding movement of drill guideassembly 62 upon upright assembly 32.

In the arrangement shown, as one example, spaced inward a distance fromslots 220, arms 66 extend rearward a distance before terminating in afree end. In the arrangement shown, as one example, a pair of arms 66are spaced a distance from one another in symmetric fashion to thecenterline or seamline 194 of drill guide assembly 62. These arms 66extend out of the plane formed by rear wall 218 in approximateperpendicular alignment to the plane of rear wall 218. Opposing arms 66extend in approximate parallel spaced relation to one another. In thearrangement shown, as one example, a support member 222 extends acrossand connects opposing arms 66 at their upper forward ends therebyproviding additional strength and support.

In the arrangement shown, as one example, the rearward ends of arms 66include a hole 148 therein that extends through opposing arms 66 inapproximate perpendicular alignment to the plane of arms 66. In thearrangement shown, as one example, arms 66 pivotally connect to thelower end of lower links 42 by inserting a pivot point 224 through theholes 148 of arms 66 as well as through hole 146 in the lower end oflower link 42 thereby connecting arms 66 and lower links 42 whileallowing for relative rotation of arms 66 and lower links 42.

In the arrangement shown, as one example, when drill guide assembly 62is installed onto upright assembly 32, arms 66 extend through forwardslot 186 in forward side 172 of covers 36. In this position, rear wall218 of drill guide assembly 62 is positioned in approximate planarsliding engagement to the plane formed by forward side 172 of covers 36of upright assembly 32. In this position, flanges 190 of covers 36 arereceived within slots 220 of drill guide assembly 62. In thisarrangement, drill guide assembly 62 may slide up and down along forwardside 172 of covers 36 guided by the planar engagement of rear wall 281of drill guide assembly 62 with the forward side 172 of covers 36 aswell as being guided by flanges 190 of covers 36 being positioned withinslots 220 of drill guide assembly 62. In this way, drill guide assembly62 may move between a non-clamping position to a clamping position alongupright assembly 32.

Drill Guide Block:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes a drill guide block 72. Drill guide block 72 may beformed of any size, shape and design and is configured to be attached toand removed from drill guide assembly 62 and includes a clamping face 74and drill guides 76 having bores 78 therein that facilitate drilling ofpocket holes in workpiece 24.

In the arrangement shown, as one example, drill guide block 72 includesa main body 226 having a clamping face 74 and an upper wall 228. Drillguides 76 having generally cylindrical bores 78 that extend therethrough extend at an angle through drill guide block 72 such that thebore 78 of drill guides 76 intersect upper wall 228 at their upper endand intersect clamping face 74 at their lower end.

In the arrangement shown, as one example, bores 78 include a passageway212 therein that extends rearward from bore 78 and through the main body226 of drill guide block 72. When drill guide block 72 is in position ondrill guide assembly 62, passageways 212 of bores 78 of drill guideblock 72 connect to passageway 210 in drill guide assembly 62 so as tofacilitate the removal of wood chips, dust and debris generated duringdrilling.

In the arrangement shown, as one example, a feature 208 is positionedadjacent the sides of drill guide block 72 that are configured toreceive and hold feature 206 of drill guide assembly 62 thereby holdingdrill guide block 72 onto drill guide assembly 62. In the arrangementshown, as one example, a connection point 216 is positioned adjacent thelower end of drill guide block 72 that is configured to engage and holdto connection point 214 of drill guide assembly 62 thereby holding drillguide block 72 onto drill guide assembly 62. In this way, thecombination of connection point 214 and connection points 216 of drillguide block 72 enables the quick, easy, convenient and secureinstallation of drill guide block 72 onto drill guide assembly 62. Inthis way, the combination of connection point 214 and connection points216 of drill guide block 72 enables the quick, easy and convenientremoval of drill guide block 72 from drill guide assembly 62.

Vacuum Attachment:

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 includes a vacuum attachment 230. Vacuum attachment 230 may beformed of any size, shape and design and is configured to be attached toand removed from drill guide assembly 62 and facilitates the removal ofwoodchips, dust and debris generated during drilling from the drillguide assembly 62 and drill guide block 72.

In the arrangement shown, as one example, vacuum attachment 230 includesan end wall 232 that connects at its upper and lower ends to upper andlower walls 234. End wall 324 also connects at its forward and rearwardends to forward and rearward walls 236. In the arrangement shown, as oneexample, end wall 232 is generally square or rectangular in shape. Inthe arrangement shown, as one example, upper and lower walls 234 extendin approximate parallel spaced relation to one another, and upper andlower walls 234 extend in approximate perpendicular alignment to endwall 232. In the arrangement shown, as one example, forward and rearwardwalls 236 extend in approximate parallel spaced relation to one another,and forward and rearward walls 236 extend in approximate perpendicularalignment to end wall 232. In the arrangement shown, as one example,upper and lower walls 234 extend in approximate perpendicular alignmentto forward and rearward walls 236. In this way, the combination of endwall 232, upper and lower walls 234 and forward and rearward walls 236form a generally square or rectangular shaped member that is configuredto fit within opening 68 of main body 64 of drill guide assembly 62.

The end of upper and lower walls 234 and forward and rearward walls 236opposite end wall 232 is connected to a neck section 238 that isconnected to a collar section 240. Neck section 238 extends in adirection away from end wall 232 and smoothly converts the generallysquare or rectangular configuration of upper and lower walls 234 andforward and rearward walls 236 to the generally cylindrical shape ofcollar section. Collar section 240 is a generally elongated cylindricalshaped member that is configured to receive the end of a conventionalvacuum. In this way, vacuum attachment 230 forms a generally hollowmember.

In the arrangement shown, as one example, one of or both of forward andrearward walls 236 include a plurality of openings 242 therein thatenable the entry of woodchips, dust and debris into the hollow interiorof vacuum attachment 230 which are then removed under vacuum by a vacuumattached to collar section 240. In an alternative arrangement, one of orboth of forward and rearward walls 236 are partially or wholly openthereby allowing unrestricted entry of woodchips, dust and debris intothe hollow interior of vacuum attachment 230.

In the arrangement shown, as one example, the end of vacuum attachment230 having end wall 232 is configured to be inserted into the opening 68in either of the sides of drill guide assembly 62. That is, vacuumattachment 230 and drill guide assembly 62 is ambidextrous. Once vacuumattachment 230 is fully inserted into opening 68, the end wall 232covers opening 68 on the side of drill guide assembly 62 opposite theside of insertion of the vacuum attachment 230. Once vacuum attachment230 is fully inserted into opening 68, vacuum attachment 230 is inposition to receive woodchips, dust and debris generated during drillingof pocket holes.

That is, during drilling of pocket holes, a drill bit is inserted withinthe bore 78 of at least one drill guide 76 of drill guide block 72. Asthe pocket hole is being drilled, woodchips, dust and debris aregenerated. The woodchips, dust and debris generated during drillingpasses from bore 78, through passageway 212 in drill guide block 72,through passageway 210 in drill guide assembly 62 and through theforward wall 236 of vacuum attachment 230. The woodchips, dust anddebris then travel through neck section 238, through collar 240 and outof vacuum attachment 230 under vacuum by an attached vacuum. In thisway, a clean, effective, convenient way of removing woodchips, dust anddebris from drill guide assembly 62.

Notably, as the drill guide assembly 62 and drill guide block 72 travelalong the angled upright assembly 32 between a non-clamping position anda clamping position, vacuum attachment 230 travels with the drill guideassembly 62 and drill guide block 72.

Some embodiments may utilize other sizes, shapes and/or designs toimplement the vacuum attachment 230. In one or more embodiments, insteadof inserting vacuum attachment 230 into opening 68, vacuum attachment230 is not inserted into opening 68. In one arrangement, vacuumattachment 230 attaches to the exterior of drill guide assembly 62 andcovers one of the openings 68 while the other opening 68 may be covered,the other opening 68 may be left open, or the other opening 68 may notbe present and instead only a single opening 68 is present.

In Operation—Example—Thin Workpiece:

With reference to FIGS. 48-56 an example is presented whereinself-adjusting pocket hole jig system 10 is used to clamp andautomatically adjust to the thickness of a thin workpiece 24. In thisarrangement, the lower end of workpiece 24 is placed on resting surface84 of lower portion 28 of base 26 and the forward face of workpiece 24is placed against clamping surface 108 of backstop 30 of base 26.

In the arrangement shown in FIG. 48 a fully unclamped position or afully non-clamping position is presented. In this position, handle 44 isin a fully raised position. Drill guide assembly 62 and drill guidecarrier 72 are in a fully raised position along upright assembly 32. Ina fully unclamped position, clutch housing 46 is in a fully loweredposition such that clutch housing 46 is positioned adjacent the lowerend of slot 162 in covers 36 as well as slot 126 in center support 34within the hollow interior of upright assembly 32.

In the arrangement shown, in FIG. 48, the axis of rotation that extendsthrough the intersection of the upper end of upper links 40 and clutchhousing 46 as well as the axis of rotation that extends through theintersection of the lower end of lower link 42 and arms 66 of drillguide assembly 62 are in alignment with one another along the centerlineof center support 34, which is shown in a dashed line. In this position,the axis of rotation that extends through the intersection of the lowerend of upper links 40 and the upper end of lower links 42 is positionedwell behind the centerline of center support 34 as well as outside ofthe hollow interior 170 of covers 36.

As is best shown, in the close-up view of FIG. 49, in a fully unclampedposition, the protrusion 130 of the upper end of upper links 40 engageand push upward upon the lower sides of clutch plates 48 thereby keepingthe clutch plates 48 from locking onto center support 34.

From the unclamped or non-clamping position, to clamp workpiece 24, allthe user needs to do is lower handle 44.

As handle 44 is rotated downward, this causes upper link 40 to rotate onthe axis of rotation that extends through the upper end of upper link 40and through the lower end of clutch housing 46. As Handle 44 is rotateddownward, this causes the lower end of upper link 40 to move downward aswell as causes the lower end of upper link 40 to rotate upon the axis ofrotation that connects the lower end of upper link 40 to the upper endof lower link 42. As the handle 44 is rotated downward, the lower end ofupper link 40 moves downward which causes the lower end of lower link 42to move downward as well.

As the handle 44 is rotated downward, the lower end of lower link 42rotates with respect to arms 66 of drill guide assembly 62 as the drillguide assembly 62 is driven downward. As the drill guide assembly 62 isdriven downward the first return spring 50 is compressed and pushesagainst the downward motion of drill guide assembly 62. As the drillguide assembly 62 is driven downward, the rear wall 218 of drill guideassembly 62 slides over the forward side 172 of covers 36 as flanges 190are held within slots 220 of drill guide assembly 62. This downwarddriving of drill guide assembly 62 continues until the clamping face 74of drill guide assembly 62 engages the rearward facing surface ofworkpiece 24, which is shown in FIG. 50.

FIG. 50 shows the point when clamping face 74 of drill guide assembly 62engages the rearward facing surface of workpiece 24. At this point, asis shown in FIG. 50, the axis of rotation that extends through theintersection of the upper end of upper links 40 and clutch housing 46 aswell as the axis of rotation that extends through the intersection ofthe lower end of lower link 42 and arms 66 of drill guide assembly 62are in alignment with one another along the centerline of center support34, which is shown in a dashed line. In this position, the axis ofrotation that extends through the intersection of the lower end of upperlinks 40 and the upper end of lower links 42 is positioned slightlybehind the centerline of center support 34.

As is best shown, in the close-up view of FIG. 51, in this position,with the clamping face 74 of drill guide block 72 engaged with therearward facing surface of workpiece 24, the protrusion 130 of the upperend of upper links 40 continues to engage and push upward upon the lowersides of clutch plates 48 thereby keeping the clutch plates 48 fromlocking onto center support 34. With that said, when comparing FIG. 49with FIG. 51, protrusion 130 has substantially moved rearward withrespect to clutch plates 48. As such, protrusion 130 is nearing thepoint where protrusion 130 disengages clutch plates 48.

With reference to FIG. 50, at this point, continued downward movement ofhandle 44 causes clamping face 74 to push into workpiece 24 therebyforcing workpiece 24 into clamping surface 108. As the handle 44continues to move downward pressure builds between clamping face 74 andworkpiece 24. This pressure builds between clamping face 74 andworkpiece 24 until enough force is applied by handle 44 that overcomesthe amount of force applied by second return spring 52 which pullsclutch housing 46 downward along center support 34. Once enough force isapplied by handle 44 to overcome the downward pull on clutch housing 46by second return spring 52, clutch housing 46 begins to slide upwardupon center support 34. As clutch housing 46 slides upward upon centersupport 34, second return spring 52 is stretched between its lowerconnection point at arm 124 of center support 34 and its upperconnection point at arms 132 which connects to the intersection ofclutch housing 46 and the upper end of upper links 40.

Clutch housing 46 continues to be driven upward along center support 34as the upper end of upper link 40 rotates. As the angle of upper link 40changes as the clutch housing 46 moves upward the relationship betweenthe protrusion 130 of the upper end of upper links 40 changes withrespect to the lower side of clutch plates 48. That is protrusion 130continues to rotate rearward as the handle 44 moves downward.

This continues to a point where protrusion 130 of the upper end of upperlink 40 disengages from clutch plates 48. This point is approximatelyshown in FIG. 52 and FIG. 53. When comparing FIG. 50 with FIG. 52,clutch housing 46 has moved higher along center support 34. As theprotrusion 130 of the upper end of upper link 40 disengages from clutchplates 48 the upward support the protrusion 130 provides to the rearwardends of clutch plates 48 is removed. This upward support provided byprotrusion 130 to clutch plates 48 counteracts the downward forceapplied on the upper side of clutch plates 48 by the spring of biasmember 160. As the support provided by protrusion 130 is removed, therearward end of clutch plates 48 is forced downward by bias member 160until clutch plates 48 lock onto center support 34. When clutch plates48 bind or lock onto center support 34 clutch housing 46 stops movingupward along 34 by the clutch plates 48 locked onto center support 34.

FIG. 52 shows the approximate point when protrusion 130 disengages fromthe lower surface of clamping plates 48. At this point, as is shown inFIG. 52, the axis of rotation that extends through the intersection ofthe upper end of upper links 40 and clutch housing 46 as well as theaxis of rotation that extends through the intersection of the lower endof lower link 42 and arms 66 of drill guide assembly 62 are in alignmentwith one another along the centerline of center support 34, which isshown in a dashed line. In this position, the axis of rotation thatextends through the intersection of the lower end of upper links 40 andthe upper end of lower links 42 is positioned just barely behind thecenterline of center support 34.

When clutch housing 46 is locked in place, as handle 44 continues torotate downward, as the upper end of upper link 44 is stationary oressentially stationary in place, essentially the only direction forrelative movement is downward and against workpiece 24. That is, oncethe clutch housing 46 is locked in place the upper end of upper link 40is locked in place. As such, as the handle 44 continues to rotatedownward, the lower end of upper link 40 continues to move downward.This downward movement of the lower end of upper link 40 causes thelower end of lower link 42 to continue to move downward. This downwardmovement of the lower end of lower link 42 causes the drill guideassembly 62 to continue to move downward, against the increasingpressure provided. This pressure is applied to workpiece 24 therebyforcing workpiece 24 against backstop 30

This continues until the handle 44 is moved such that the axis ofrotation between the lower end of the upper link 40 and the upper end ofthe lower link 44 move to an over-center condition, which is shown inFIG. 54 and FIG. 55, at which point stop bar 138 engages the rearwardside of center support 34 thereby preventing any further downwardmovement of handle 44. In this over-center condition, upper link 40 andlower link 42 and handle 44 are naturally held in place as the forcesgenerated through clamping have a tendency to force stop bar 138 intothe rearward side of center support 34.

FIG. 54 shows the approximate point when protrusion stop bar 138 engagesthe rearward side of center support 34 in an over-center condition ofclamping assembly 38. At this point, as is shown in FIG. 54, the axis ofrotation that extends through the intersection of the upper end of upperlinks 40 and clutch housing 46 as well as the axis of rotation thatextends through the intersection of the lower end of lower link 42 andarms 66 of drill guide assembly 62 are in alignment with one anotheralong the centerline of center support 34, which is shown in a dashedline. In this position, the axis of rotation that extends through theintersection of the lower end of upper links 40 and the upper end oflower links 42 is positioned just forward the centerline of centersupport 34—which is an over-center condition.

When in an over-center condition, clamping face 74 of drill guide block72 is in flat and flush and tight engagement with the rearward face ofworkpiece 24. This allows a user to easily and securely drill pocketholes in workpiece 24 through bores 78 formed by drill guides 76 indrill guide block 72. As the pocket holes are drilled, woodchips, dustand debris travels through passageways 212 in bores 78 in drill guideblock 72 and into the passageway 210 in drill guide assembly 62 undervacuum applied through vacuum attachment 230 inserted within an opening68 in a side of main body 64. The woodchips, dust and debris are pulledinto the vacuum attachment 230 under vacuum and are pulled through thehollow interior of vacuum attachment 230 and out the collar section 240thereby removing the woodchips, dust and debris from the drill guideblock 72 and the drill guide assembly 62. This makes the process ofdrilling pocket holes cleaner and easier while also improving thequality of the pocket holes by removing the interference caused bywoodchips, dust and debris generated during drilling.

Once drilling is completed, all the user needs to do to release andremove the workpiece 24 is lift up on the outward end of handle 44 whichcauses the upper link 40 and lower link 42 to move out of an over-centercondition as the handle 44 is raised. As the handle 44 is raised, theprotrusion 130 pushes up on the rearward end of clutch plates 48 andupon overcoming the spring bias force applied by bias member 160 therebybreaks the locking engagement between clutch plates 48 and centersupport 34. Once the locking engagement between clutch plates 48 andcenter support 34 is broken, the clutch housing 46 is automaticallypulled downward by the tension of second return spring 52 while thedrill guide assembly 62 is automatically pushed upward by first returnspring 50, all while handle 44 is automatically pulled upward by thecombined spring force of first return spring 50 and second return spring52. This motion automatically continues, in the reverse manner describedwith respect to clamping motion, until the clamping assembly 38 movesback to a fully unclamped or a fully non-clamped position, at whichpoint the workpiece 24 may be removed and the self-adjusting pocket holejig system 10 is ready for clamping again in the same way describedherein.

One of the benefits of self-adjusting pocket hole jig system 10 is thatas the handle 44 is lowered the clamping face 74 of drill guide block 72remains vertical, or said another way, parallel to the rearward facingsurface of workpiece 24 throughout the clamping motion. That is as thehandle 44 is lowered with a single motion the clamping face 74 movesdownward and forward while maintaining a perpendicular alignment to therearward facing surface of workpiece 24. In this way, engagement of theclamping face 74 onto the rearward facing surface of workpiece 24effectively applies a forward clamping force on the workpiece 24 that isperpendicular to the rearward facing surface of workpiece 24 with littledownward force. In this way, the clamping motion of self-adjustingpocket hole jig system 10 does effectively not impart a rotational forceupon workpiece 24 as does other clamping systems. In addition, theclamping force of self-adjusting pocket hole jig system 10 is centeredupon the area where bores 78 of drill guides 76 intersect with workpiece24 thereby ensuring the clamping pressure is applied by self-adjustingpocket hole jig system 10 at the optimal position to ensure drilling ofthe most accurate and clean pocket holes in the safest possible manner.

One of the benefits of the self-adjusting pocket hole jig system 10 isthat the handle 44 moves only in a single plane. That is, the user mayclamp and unclamp self-adjusting pocket hole jig system 10 by movinghandle 44 downward (for clamping) and upward (for unclamping) in asingle plane. This single plane of motion, using only handle 44 iseasier on the user and more ergonomic. In addition it is simpler to useand learn as compared to a multi-movement process, not to mentionfaster. In addition, the user may clamp and unclamp by placing theirhand on only a single component, the handle 44, which eliminates theneed to grasp and manipulate multiple devices, as is required by otherprior-art jigs. As such, the speed, comfort and ease of use of theself-adjusting pocket hole jig system 10 is unmatched.

In Operation—Example—Thick Workpiece:

With reference to FIGS. 57-61 an example is presented whereinself-adjusting pocket hole jig system 10 is used to clamp andautomatically adjust to the thickness of a thick workpiece 24. In thisarrangement, the self-adjusting pocket hole jig system 10 operates inthe same manner described herein, with the difference being the drillguide assembly 62 engages the workpiece 24 earlier which is accommodatedby the clutch housing 46 moving upward along center support 34 earlierin the clamping process. In this way, approximately the same clampingpressure is applied when clamping both thin or thick workpieces 24, orfor that matter, approximately the same clamping pressure is applied toany thickness of workpiece 24 automatically by way of automatic internaladjustments made automatically within the self-adjusting pocket hole jigsystem 10 without user intervention. That is, the user experience as itapplies to clamping is practically identical for clamping any sizedworkpiece 24 and requires no user adjustments.

As such, FIG. 48 and FIG. 49 is similar to FIG. 57; FIG. 50 and FIG. 51is similar to FIG. 58; FIG. 52 and FIG. 53 is similar to FIG. 59; FIG.54 and FIG. 55 is similar to FIG. 60; and FIG. 56 is similar to FIG. 61.The close-up views of FIGS. 49, 51, 53 and 55, are not repeated for thethick clamping example as the teaching as it applies to the position ofprotrusion 130 is functionally similar albeit with a different positionof components along the length of center support 34.

The only user adjustment that may be made to adjust operation of theself-adjusting pocket hole jig system 10 is rotation of knob 56 of clampforce adjustment mechanism 54 which increases or decreases the clampingpressure applied to workpieces 24. The adjusted clamping pressure as setby rotation of knob 56 of clamp force adjustment mechanism 54 is thenapplied to all workpieces 24 of any thickness without any further useradjustment.

Grippy Material:

In one arrangement, some or all of the surfaces of system 10 that engageworkpiece 24 are partially or wholly covered by a compressible materialthat has a high coefficient of friction or a non-compressible materialthat has a high coefficient of friction. This material with a highcoefficient of friction is referred to herein as a grippy material andhelps to hold workpiece 24 in place within jig 10 as well as reduces theamount of clamping pressure required to adequately hold workpiece 24 inplace. This is because this grippy material has a high coefficient offriction making it less likely that workpiece 24 will slide or shiftafter being clamped and during the drilling process.

In one arrangement this grippy material with a high coefficient offriction covers some or the entire upward facing resting surface 84 oflower portion 28 of base 26, the rearward facing clamping surface 108 ofback stop 30 of base 26 and/or the clamping face 74 of drill guide block72. The entirety of these surfaces may be covered by a grippy materialor alternatively only a portion of these surfaces may be covered by agrippy material. The grippy material may be added on top of thesesurfaces by gluing, adhering, spraying, sticking or otherwise by addingthe grippy material by any other manner, method or means. Alternatively,the grippy material may be formed into these surfaces duringmanufacturing such as through dual durometer molding or otherwise byadding the grippy material by any other manner, method or means.

Alternative Arrangement—Benchtop Arrangement:

FIGS. 1-61 show an embodiment of self-adjusting pocket hole jig system10 that includes base 26 that is attached to, and integral with, uprightassembly 32. In an alternative arrangement, it is hereby contemplatedthat self-adjusting pocket hole jig system 10 may be used without base26. In this arrangement, upright assembly 32 is installed onto anothercomponent, such as a benchtop or work bench, that serves as base 26having a horizontal portion and a vertical portion that serve as lowerportion 28 and back stop 30 of base 26 as is shown herein. Once uprightassembly 32 is installed onto such as benchtop or work bench, theself-adjusting pocket hole jig system 10 operates in the mannerdescribed herein. In one arrangement, to facilitate easier installationof upright assembly 32 onto a benchtop, the lower surface of platform180 is flat so as to easily install onto a benchtop such as by theinsertion of screws or bolts through the through holes 182 in thecorners of platform 180 and into the benchtop.

Alternative Arrangement—Automaxx Self-Adjusting Clamping Mechanism:

With reference to FIGS. 62-74 an alternative arrangement ofself-adjusting pocket hole jig system 10 is presented. This alternativearrangement presented in FIGS. 62-74 is similar to the self-adjustingpocket hole jig system 10 is presented in FIGS. 1-61, and therefore,unless specifically stated otherwise, the teachings presented hereinapply to the embodiment presented in FIGS. 62-74.

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 utilizes a self-adjusting clamping mechanism 244 similar tothat presented in Applicant's U.S. patent application Ser. No.15/188,151 entitled Self-Adjusting Clamp System filed on Jun. 21, 2016and published as US 2016-0368119 A1 on Dec. 22, 2016 which is fullyincorporated by reference herein. This product is sold by Applicantunder the trademark Automaxx. In this arrangement, as one example,self-adjusting clamping mechanism 244 includes a wedge lock 246 and anactivator wedge 248 which are separated by a separation plate 250 suchas that presented in the incorporated by reference patent application.The self-adjusting clamping mechanism 244 self-adjusts and facilitatesclamping in the manner described by the incorporated by reference patentapplication in association with the modifications presented herein withthe association of clamping assembly with upper link 40, lower link 42,handle 44, base 26 and drill guide assembly 62 and drill guide block 72as well as the other features and components presented and described andshown herein.

Alternative Arrangement—Ratcheting Self-Adjusting Clamping Mechanism:

With reference to FIGS. 75-89 an alternative arrangement ofself-adjusting pocket hole jig system 10 is presented. This alternativearrangement presented in FIGS. 75-89 is similar to the self-adjustingpocket hole jig system 10 is presented in FIGS. 1-74, and therefore,unless specifically stated otherwise, the teachings presented hereinapply to the embodiment presented in FIGS. 75-89.

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 utilizes a self-adjusting clamping mechanism 252 thatinteracts with a ratchet surface 254 in an interior side 256 of theforward wall 258 of upright assembly 32 opposite forward side 172. Inthis arrangement, as one example, self-adjusting clamping mechanism 252includes a carrier 260 that slides up and down within upright assembly32 and includes a clutch member 262 that interacts with teeth of theratchet surface 254 positioned on the interior side 256 of forward wall258. The self-adjusting clamping mechanism 252 self-adjusts andfacilitates clamping in a similar manner to that described herein withthe clamping assembly 32 having an upper link 40, lower link 42, handle44, base 26 and drill guide assembly 62 and drill guide block 72 as wellas the other features and components presented and described and shownherein with the addition that upon clamping, the lower end of clutchmember 262 pivots forward under the force of protrusion 130 at the upperend of upper link 40 and engages at least one tooth of the ratchetsurface 254 with at least one tooth of its own thereby locking thecarrier 260 in position along upright assembly 32.

Alternative Arrangement—Spring and Tube Self-Adjusting ClampingMechanism:

With reference to FIGS. 90-103 an alternative arrangement ofself-adjusting pocket hole jig system 10 is presented. This alternativearrangement presented in FIGS. 90-103 is similar to the self-adjustingpocket hole jig system 10 is presented in FIGS. 1-89, and therefore,unless specifically stated otherwise, the teachings presented hereinapply to the embodiment presented in FIGS. 90-103.

In the arrangement shown, as one example, self-adjusting pocket hole jigsystem 10 utilizes a self-adjusting clamping mechanism 264 having acylindrical tube 266 with a spring 268 positioned around tube 266 andconstrained between an upper stop surface 270 and a lower stop surface272. A collar 274 is connected to the upper end of upper link 40. Collar274 is positioned above lower stop surface 272 and the lower end ofspring 268. Spring 268 is constrained between the upper surface ofcollar 274 and the upper stop surface 270. In one arrangement, a secondspring 276, like first return spring 50 is used to force drill guideassembly 62 upward to a non-clamping position.

In this arrangement, as handle 44 is lowered after workpiece 24 isengaged, collar 274 begins to move upward along tube 266 untilprotrusion 130 engages the side of tube 266 at a slightly over-centercondition thereby clamping and locking workpiece 24 in place betweenclamping face 74 and backstop 30.

Alternative Arrangement:

With reference to FIG. 105-123 an alternative arrangement of aself-adjusting pocket hole jig system 10 is presented. This alternativearrangement of a self-adjusting pocket hole jig system 10 presented inFIG. 105 through FIG. 123 is similar to the configuration ofself-adjusting pocket hole jig system 10 presented in FIG. 1 throughFIG. 61. For this reason, unless specifically stated otherwise, all ofthe teaching and disclosure presented with respect to the arrangementpresented in FIG. 1 through FIG. 61 applies equally to the arrangementpresented in FIG. 105 through FIG. 123. In addition, unless specificallystated otherwise, while the embodiments are different, all of theteaching and disclosure presented with respect to the arrangementspresented in FIG. 62-104 apply equally to the arrangement presented inFIG. 105-123.

The alternative arrangement presented in FIG. 105-123 is a revision tothe arrangement presented in FIG. 1 through FIG. 61.

Grippy Material:

In one arrangement, some or all of the surfaces of self-adjusting pockethole jig system 10 that engage workpiece 24 are partially or whollycovered by a compressible material that has a high coefficient offriction. This compressible material with a high coefficient of frictionhelps to hold workpiece 24 in place within self-adjusting pocket holejig system 10 as well as reduces the amount of clamping pressurerequired to adequately hold workpiece 24 in place. This is because thisgrippy material has a high coefficient of friction making it less likelythat workpiece 24 will slide or shift after being clamped.

In one arrangement, this compressible material and/or material having ahigh coefficient of friction, covers some or all of the upper surface orresting surface 84 of lower portion 28 of base 26, the clamping surface108 of backstop 30, and/or the clamping face 74 of drill guide block 72or any combination thereof. In contrast, the material that forms theunderlying components, e.g. base 26, lower portion 28, backstop 30,drill guide block 72, is formed of a hard and rigid and durablematerial, such as a plastic, nylon, metal or the like. While these hard,rigid and durable materials provide a strong jig 10, they do not have ahigh coefficient of friction. As such, additional clamping pressure isrequired to secure workpiece 24 in place. The addition of a grippymaterial having a higher coefficient of friction as compared to theunderlying material of jig 10 reduces the clamping pressure required tosecure the workpiece 24.

This grippy material may be molded onto jig 10, formed as part of jig10, adhered to jig 10, sprayed on jig 10, deposited on jig 10, connectedto jig 10 or added in any other manner, method or means or anycombination thereof. In the arrangement shown, as one example, thisgrippy material is added as a grip pad 300 placed on clamping surface108 that covers most of clamping surface 108 of backstop 30. In thisway, when a workpiece 24 is clamped in place, drill guide block 72forces workpiece 24 against grip pad 300. The high coefficient offriction of grip pad 300 helps to hold workpiece 24 in place. Thepresence of grip pad 300 provides greater grip at the same clampingforce as compared to grip pad 300 or grippy material not being presentand instead the workpiece 24 engaging the hard, rigid and durableunderlying material of jig 10.

Clamp Recess 302:

In the arrangement shown, as one example, with reference to FIG. 105through FIG. 123 self-adjusting pocket hole jig system 10 includes oneor more clamp recesses 302. Clamp recess 302 is formed of any suitablesize, shape and design and is configured to receive a portion of aclamp, such as a conventional C-clamp, project clamp, or any other formof a clamp, therein so as to facilitate clamping of self-adjustingpocket hole jig system 10 to a work surface, such as a table, bench,board, sawhorse, or the like.

In the arrangement shown, as one example, clamp recess 302 is a t-shapedslot or a square-shaped opening or a rectangular shaped opening, or anyother opening that extends inward a distance into self-adjusting pockethole jig system 10 and receives a portion of a clamp therein thatfacilitates clamping of the self-adjusting pocket hole jig system 10 inplace. This clamp recess 302 is configured to receive an arm of a clamptherein thereby allowing jig system 10 to be clamped to a work surfacein a convenient, easy, simple, safe and secure manner. Furtherinformation regarding clamp recess 302 is more fully presented inApplicant's U.S. Provisional Patent Application No. 62/950,189 filedDec. 19, 2019, entitled: “DOCKING STATION SYSTEM” which is fullyincorporated by reference herein. However, other sizes, shape and designis hereby contemplated for use as clamp recess 302

In the arrangement shown, as one example, a clamp recess 302 ispositioned in the rearward end 82 of lower portion 28 of base 26. Thisclamp recess 302 enables self-adjusting pocket hole jig system 10 to beclamped from its rearward end in an upright manner. This is useful fordrilling on small to medium sized workpieces 24.

In the arrangement shown, as one example, a clamp recess 302 ispositioned in the forward end of lower portion 28 of base 26 at theintersection of lower portion 28 of base 26 and backstop 30 of base 26.This clamp recess 302 enables self-adjusting pocket hole jig system 10to be clamped from its forward end in an upright manner. This is usefulfor drilling on small to medium sized workpieces 24.

In the arrangement shown, as one example, a clamp recess 302 ispositioned in the upper end 110 of backstop 30 of base 26. This clamprecess 302 enables self-adjusting pocket hole jig system 10 to beclamped from its forward end in a horizontal manner as compared toclamping using the other clamp recesses 302 in lower portion 28 of base26. That is, using clamp recess 302 in the upper end 110 of backstop 30of base 26 allows for self-adjusting pocket hole jig system 10 to beclamped in a 90° orientation as compared to using the other clamprecesses 302 in the lower portion 28 of base 26. This is useful fordrilling on large or long workpieces 24 such as large sheets of plywoodand long lengths of dimension lumber.

Wings 304:

In the arrangement shown, as one example, with reference to FIG. 105through FIG. 123 self-adjusting pocket hole jig system 10 includes oneor more wings 304. Wings 304 are formed of any suitable size, shape anddesign and are configured to move between a retracted position, whereinwings 304 are tucked into the sides 80 of lower portion 28 of base 26,and an extended position, wherein wings 304 are extended or pivotedoutward from the sides 80 of lower portion 28 of base 26. In thearrangement shown, as one example, a wing 304 is connected to each side80 of the lower portion 28 of base 26 adjacent the resting surface 84.In the arrangement shown, as one example, the upper surface 306 of wings304 extend in a generally flat and flush parallel planar alignment tothe resting surface 84 of lower portion 28 of base 26. In this way,regardless whether wings 304 are extended or retracted the upper surface306 of wings 304 are flat and flush with the resting surface 84 of lowerportion 28 of base 26. In this way, the presence of wings 304 does notdisturb the resting surface 84 of lower portion 28 of base 26, andinstead, the presence of wings 304 can extend the resting surface 84 oflower portion 28 of base 26.

In the arrangement shown, as one example, the forward end 308 of wings304 connect to the lower portion 28 of base 26 at a pivot point. Thisconnection of wings 304 to lower portion 28 of base 26 at a pivot pointat forward end 308 allows wings 304 to rotate between a retractedposition, wherein wings 304 are tucked in along the sides 80 of lowerportion 28 of base 26, and an extended position, wherein wings 304 areextended in an approximate perpendicular alignment to theforward-to-back length of lower portion 28 of base 26.

In this extended position, the upper surface 306 of wings 304 extend thesupport for workpiece 24 out to the side of lower portion 28 of base 26the length of wings 304. This provides additional support for longerworkpieces 24.

In the arrangement shown, as one example, a plurality of supports 310extend downward from upper surface 306 of wings 304 and establish aplane at their lower end that wings 304 rest upon when placed on a worksurface such as a bench, table or the like. In this way, supports 310provide strength and rigidity to wings 304 as well as stability to wings304.

In the arrangement shown, as one example, recess 312 is placed justrearward of the rearward end 314 of wings 304 in the side 80 of lowerportion 28 of base 26. This recess 312 is configured to allow a user toplace their finger or a tool into contact with the rearward end 314 ofwing 304 so as to move wing 304 from a retracted position to an extendedposition. To move wing 304 from a retracted position to an extendedposition, as well as to move wing 304 from an extended position to aretracted position, the wing 304 may simply be rotated into positionupon the pivot point established by the connection between lower portion28 of base 26 and forward end 308 of wing 304. As such, extending andretracting wings 304 is quick, easy and user friendly.

In one of more embodiments, the connection between the forward end 308of wings 304 and lower portion 28 of base 26 has sufficient friction tohold wing 304 in the user-set extended position. That is, wings 304remain in an extended position until a user moves them to a retractedposition. Similarly, in the arrangement shown, as one example, theconnection between the wings 304 and lower portion 28 of base 26 hassufficient friction to hold wing 304 in the user-set retracted position.That is, wings 304 remain in a retracted position until a user movesthem to an extended position. As such, this prevents unintentionalmovement of wings 34. Additionally or alternatively, in one or moreembodiments, the base 26 and/or wings may include a locking mechanismconfigured and arranged to lock wings in an extended and/or retractedposition.

Center Support 34:

In the arrangement shown, as one example, with reference to FIG. 105through FIG. 123 self-adjusting pocket hole jig system 10 includes acenter support 34. In the arrangement shown, as one example, withreference to FIG. 105 through FIG. 123, center support 34 extendsthrough upright assembly 32, through lower portion 28 of base 26 andthrough backstop 30 of base 26. In the arrangement shown, as oneexample, center support 34 is formed of a strong, rigid and durablemetallic material. In contrast, upright assembly 32, lower portion 28 ofbase 26 and backstop 30 of base 26 may be formed of a non-metallicmaterial such as a plastic, a nylon, a composite, a fiberglass or anyother non-metallic material or any combination thereof. While uprightassembly 32, lower portion 28 of base 26 and backstop 30 of base 26 areformed of strong and rigid materials, the addition of center support 34extending through all of these components provides additional strengthand rigidity.

In particular, by having center support 34 extend upward within backstop30 of base 26, this substantially prevents or reduces the flexion ofbackstop 30 when clamping force is applied by clamping assembly 38 ontoworkpiece 24 which applies force onto backstop 30 of base 26. That is,by completing the U-shaped profile of center support 34, and extendingcenter support 34 through all of upright assembly 32, lower portion 28of base 26 and backstop 30 of base 26 this increases the strength andrigidity of the self-adjusting pocket hole jig system 10 and increasesthe accuracy of the pocket holes it drills by reducing or eliminatingflexing of the system 10 under clamping pressure.

Storage Features 316:

In the arrangement shown, as one example, with reference to FIG. 105through FIG. 123 self-adjusting pocket hole jig system 10 includesstorage features 316. Storage features 316 are formed of any suitablesize, shape and design and are configured to hold and store componentsthat are needed or useful when using self-adjusting pocket hole jigsystem 10.

In the arrangement shown, as one example, storage features 316 arepositioned in the forward side of backstop 30. In the arrangement shown,as one example, storage features 316 are sized and shaped tofrictionally hold a stepped drill bit 318 and stop collar 320, Allenwrench 322, short driver 324 and long driver 326 therein among any othertool, part, component or the like.
